What happened?

When I try to add QWebEngineView(), the theme does not display correctly for both DARK and LIGHT.

If i remove the QWebEngineView(), then theme works as expected.

Operation System

Window 11

Python Version

3.11

PyQt/PySide Version

PySide6

PyQt/PySide-Fluent-Widgets Version

v1.3.2

How to Reproduce?

adding web view makes the theme break

Create a splitter and add QWebEngineView and table to it

    self.splitter = QSplitter(Qt.Horizontal)
    self.splitter.addWidget(self.webView)
    self.splitter.addWidget(self.table)

but if you comment the web view. theme works fine but then missing the webview

Create a splitter and remove QWebEngineView

    self.splitter = QSplitter(Qt.Horizontal)
    ##self.splitter.addWidget(self.webView)
    self.splitter.addWidget(self.table)
